Ever seen works by Raphael, Michelangelo, Rubens, Boucher, Van Eyck? No nude Christ child or angel can be considered pornography. Or Rembrandt's peeing infant Ganymedes that is abducted by Zeus in the shape of an eagle? But times have changed, the pendulum is now at about the end of the conservatist movement for whom even mysticism is either pure sex or something you can make money from. And usually both. The only way you can do something about it is by stopping to spend money. Don't buy anymore. That way Ebay/Paypal and other bigger and smaller moneymakers will change their minds quickly. But you must face the consequences as sites like Rederosity and Daz thrive on their marketplaces. And many merchants would lose an income. Or you could start a site of your own, and come here to ask the necessary questions in case you have something you don't understand. My friend is also a mod at a photoshop forum. Once they removed an image with link to real a "pornography" site. But usually they ask the creator to remove it her/himself, explaining why. moderating a forum is not easy, and it's done by humans. With preferences, and sometimes personal vendettas. Just like in real life. Not every police officer is a friendly "uncle copper".
